An analysis published in the Nutrition Journal suggests that an increased consumption of riboflavin, vitamin B2, is associated with a lower risk of developing osteoporosis. Data was collected from over 4,000 women participating in the National Health and Nutrition Examination Survey (NHANES), a cross-sectional representative study of the U.S. population, including estimates of riboflavin intake as well as dual-energy X-ray absorptiometry (DXA) measurements of femur bone mineral density (BMD).
